Application filed May 1, 1912. Serial No. 694.31?.

.'Be it known that I', JrLixN A. GiLEs, a citizen ofthe United States ofAmerica, and resident of Derby, county of New Haven. and State ofConnecticut, have invented certain new and useful Improvements inPaper-Box Machines, of which the following is a specification.

- My invention relates to box'niachines, and indre particularly to thatclass of box niachines in which paper boxes are made from a; continuousweb or roll of paper fed into the machine automatically' and punched,

scored, folded and glued automatically.

'-lheobject of niy invention is toprovide a-nichine of this class whichshall vbe siniple and effective iii its construction and operation.

My invention consists in a novel ineans for feeding and applying glue,iii novel means for punching and .scoring 4the blanks` ih a novelineaiis for folding or forming the coinplete box froin the blanks, andin other novel.,f eatiiies to be hereinafter fully pointed out-fanddescribed.

The refei'uice characters are used in the saine sense throughout thedrawings and specication.

The inachine here illustrated is double and capable of making two boxesof diierent sizes or a box and its cover simultaneously. inany of thepaits of the inachine serving during a part of a revolution or c vcle toperform their function on the box being ma de at one end of theniacliiiie and at another part of the revolution or cycle to perform thesaine function on the box being niade at the other end of the niacliine.thereby eifecting a considerable econoiny in space, tiine and cost..

Numeral l represents the niain franie of the machine` which is of thebox girder forni and supported by the legs 2. Secured to the top of thetrahie are the brackets 3 having capped bearings 4 forined therein inwhich operates the inaiii driving or crank shaft 5, having the crank 6formed thereon, which operates to reciprocate the slide 7, theconstruction and functions of which will be described hereinafter. Atoneend of t-lie shaft is mounted the driving pulley 8. which is adapted tobe driven by a belt or in any other convenient manner, and it isconnected to the shaft by a clutch, the details of which are not shownas they forni no part of my present invention. The clutch is operated bythe lever 9 connected with the handlelO. At the side of the pulley S andsecured thereto is a smaller pulley 1l which revolves continuously withthe pulley 8 andthe pulley l1 connected by the belt l2 to the pulley 13which in turn is connected by the belt 14 to the pulley l5, the pulley13 driving the glue roll 1G at one end of the niachinc and the pulley lodriving the glue roll 1T at the other end of the machine. All ofth'enioving parts of the iiiachiiie except the glue rolls derive theirmotion froin the shaft, 5. It will therefore be seen that the glue rollsare kept continuously iii inotion even when the clutch is thrown out.and the other moving parts of the iiiachine are at rest. The purpose ofthis feature of iny in vention is t'o avoid an uneven distribution of ior another,

machine and considerable diliicu'lty has been.'y

that it is necessaryI to stop'tnev experienced .because of thetendencyof the glue 'to dry quickly and unevenlyupon the. glue rollsduring such time. t

The continuous roll or web 18 of paper -or other suitable material` ofwhich the boxes are .to be made is supported as by the vshaft 19 or' inany convenient manner and is yled up over a guide bar 20, over the roll21, under the roll 22 andbetween it and the roll 23. vThe rolls 21 and22 are mounted v are. adapted Vto slide inthe opening l25.

- The web 18 is led through the guide 36 up in front of the punching andscoring die 37 and in front ofthe forming die i' (s Figs.' In front ofthe punchingv and scoring die the notches 39 see Fig. 18) [whichseparatethe corner 'flaps 40 from the end flaps 41, are punched out andthe scores `orcre`ases42 on which the corner aps are bent and the scoresor creases 43 and 44 on which the end flaps 41 and'side flaps 45respectively are bent, vare formedfas will be 'more fully hereinafterexplained.'

The glued surfaces or vspot-S46 on the end flaps are applied as the. webpasses under. the roll 22. This is-accomplished asfollows: The gluerolls 17 are of thewidth re- 1 basin 50. Springs 5 .49 engage the Atops5 vtionthe glue rolls 17 revolve clear of the quired for'the gluedsurfaces 46. They are mounted on the shaft 47 which revolves .in thebearings 48. These bearingsar'e slidably mounted in vertical guides 49in the glue 1 mounted in the guides of the bearings 48v and tend to keepthe bearings 'in their lower.

position. The sliding vpins 52 inthe end` webs of the glue basinproject' a short-distance below the bottom of the basin ard engage vthebearings 48 at their upper ends. NVh'en the bearings are in their lowerposil web18 and they are raised into contact with v-the'web by meansofthe levers 53, which are secured tothe shaft 54 mounted in the. frameAor 4legs ofthe machine and adapted to en- A- certain limits the length-by means'of the Acams 55 secured to the end of the shaft 34,- thellevers 56 being 2secured camrollers 59 at thei'riupper ends whichengage the cams 55.,y The cam rollers are kept in Contact with the camby means 'of a spring 57; I prefer to make the cams 55 of two similarparts having slottedholes 58 by in different relations, 59 are made longy enough to span 'both parts. By this means it is possible to adjustwithin face on the eb.

By means ofthis arrangementthe glue rolls, the lower edges of which dip into theglue, are volving. In the intermittent feeding of the web..` by.; means;-of the radially grooved wheels 31 on the shaft 30 and thepin 32 in thegear wheel`33 abovel described,'the 4web startsy slowly and speed andthen graduallyyslows down' again 'toward the end of lits movement andthe speed' of` the periphery of the glue rolls 17 is arranged tobe`about the same as that' of the web when the"`glue roll "first makescontact with the web.

The glue basin 50 is provided with extensions 67 which rest upon thesupports 68 in the frame, and the shaft 62 being mounted in bracketsecured to the fr'ame While the shaft 47, which carries the glue rolls,being mounted in the glue basin, this construction permits the gluebasin with the glue rolls to be xWithdrawn at any time forA the purposeof cleaning or renewing the glue supply Without disconnecting any partsor even Without the necessity of stopping the machine. y i' The punchingand scoring of the blank is accomplished by the movable die 70coperating with the stationary die 37, above referred to, and thefolding or forming is accomplished by the movable plunger 71'cooperating with the stationary fprming die 38 above referred to. Thepunching and scoring movable die 7G and the plunger 7l are both securedto the reciprocating slide 7 above referred to, which 1s reciprocatedback and forth horizontally by means of the crank 6 on the shaft 5, thesliding blocks 73 operating in the vertical guides 74 of the slide 7 ina manner which is Well understood. The stationary punching and scoringdie 37 is secured to the forming die 38 which latter isl secured to thebracket 75. The bracket 75 rests upon and is secured to the frame or bedl by the bolts 76 and it is adjusted and held in position longitudinallyby the adjusting screw 77. The stationary punching and scoring die 37comprises two arallel pieces 78'and 79, the central mem.- ber 80, thescoring blades 81 and the stripper 82. The movable punching' and scoringdie 70 which coperates with the stationary die above referred to. issecured to the reciprocating slide 7 and comprises the die block 83. thefour punching blades 84. the corner flap scoring blades S5. the end flapscoring blades 86, the retaining blocks '87, the side strippers 88, andthe central stripper 89. The three parts 78. 7 9

'and 80 of the stationary die are made of hardened steel the top edge ofthe upper side piece 78 forming a cutting edge vfor the shearing blade.which severs the blank from the end of the web. Therecesses 90 formedbetween the adjacent ends of the pieces 78.

At the inner ends of the slots or openings inthe stationary punching and scoring die 37. I provide sniaii squarepieces 98 to form the cutting edge for the end of the slot and theblades 81 are inserted 'in a groove or space between `these pieces.These blades project a slight distance only above the face of the dieand are adjusted by means of the screws 94, and they coperate with theflat surface' of thedie block 83 to cut slightly into the web to formthe longitudinal scores for the bending of the side flaps; The stripper82 is made of thin sheet steel and its edges project above the blades 81and the strippers 88 and 89 of the movable die are also made of sheetsteel and their ends project beyond the face of the cutting punches 84.so that when a blank is punched and scored b v the dies; as the movabledie recedes the blank- Will be freed from both dies.

.The reciprocating slide 7 is provided with the projections at its sideswhich fin-m guides for the cutter slide 96. The cutter 'slide carriesthe cutter blades 97 which co operate with the upper vouter edge of thepiece 78 of the Stationary die 37 to shear off or sever the blank afterit has been punched and scored. The cutting. edge of the cutterblade 97is made concave (see Figs. 2 and l2) so that it shears the outer edgesof the Webbefore the central part thereof. This slide is actuated by thecams or lugs 98 secured to the main shaft 5. which coperatie with theblocks 99 secured to the slide in the cent-ral opening 100 thereof (seeFigs. 7 and 9 for instance).` The. slide 96 is providedwith bores 101 inwhich operate the plungers 10'2 which are pressed out wardly by thesprings 103. The ends of the plungers 10Q are adapted to engage theinwardly projecting end of Athe bearing 4. As the cam 98 forces theslide 96 in one direction the spring behind the plunger on the oppositeside of the shaft is compressed and when the cam passes o ut ofengagement with the lue 99 the spring immediately returns the slide toits central position. as will be readily understood b v the drawing.

Secured to the slide 7 above the punching and scoring die 70 is theforming plunger 71 above referred to. This plunger has an end ofrectangular shape substantially identical with the shapeof the-bottom ofthe invside of the box, 4and cooperates with the'v Aforming die 38 tofold the flaps of th`e blank and press the glued surfaces together tocomplete the formation of -the box.
